Introduction to proofs: Identifying geometry theorems and postulates ANSWERS C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? PR and PQ are radii of the circle. Therefore, they have the same length. A triangle with 2 sides of the same length is isosceles. 2) Why is an altitude? AB = AB (reflexive ...
The following five steps are used to give geometric proofs: The Proof Process 1. Write the conjecture to be proven. 2. Draw a diagram if one is not provided. 3. State the given information and mark it on the diagram. 4. State the conclusion of the conjecture in terms of the diagram. 5. Plan your argument and prove your conjecture.
Proofs Worksheet #1 On a separate paper, write a two-column proof for each problem 1-5. Follow the plan provided for help. 1. Given: RT SU≅ Prove: RS = TU Plan: Use the definition of congruent segments to write the given information in terms of lengths. Next use the Segment Addition Postulate to write RT in terms of RS + ST and SU as ST + TU.

Day 6—Algebraic Proofs 1. Solve the following equation. 2. Rewrite your proof so it is “formal” proof. Justify each step as you solve it. 2(4x - 3) – 8 = 4 + 2x 2(4x - 3) – 8 = 4 + 2x Proof: An argument that uses logic, definitions, properties, and previously proven statements to show a conclusion is true
